## coefficient

1. Maths
a. a numerical or constant factor in an algebraic term
b. the product of all the factors of a term excluding one or more specified variables
2. Physics a value that relates one physical quantity to another

## Coefficient

a numerical factor in a literal expression, a known multiplier of an unknown quantity of any degree, or a constant multiplier of a variable quantity. Thus, in the monomial −¾ a2b3 the coefficient is −¾; in the equation x2 + 2px + q = 0 the coefficient of x2 is 1 and the coefficient of x is 2p; and in the formula for the circumference of a circle l = 2πr the coefficient is 2π. In the equation for a straight line y = kx + b, the number k, which expresses the tangent of the angle that the line makes with the Ox axis, is known as the slope. Many of the coefficients in formulas expressing physical laws have special names, for example, the coefficient of friction and the coefficient of light absorption.

An aquifer to be able to transmit water in a high level is base on the permeability and hydraulic conductivity of the rock, in Rivers State geological formation, the permeability of the rocks are very high which allow for easy transmission of water at a very high volumes, because the formation is very porous, therefore this storage coefficient are very high and these conditions allowed the possibility of transmitting and storing of large volume of water at the aquiferous zone, therefore the ability of an aquifer to transmit volume of groundwater are calculated by multiplying the hydraulic conductivity by the aquifer thickness.
